. iliacnmn FORMAKING CHECK-iBooKcovnas.

T all whom it may conoci/oi Be it known that I, CHARLnsll-l. Knaus-3 Gimna citizen of the United States, residingat Portland, in the `county of Multnoj mah and State `of Oregon, have invented `certain new and useful 'Improvements in Machines for MakingCheck-Book Covers,

i p of which the following is a specification.

s At the present time, covers of check books, tablets, and the like, are made up of cardboard sides connected by gummed cloth.`

The cardboard stock usedfin making covers of this sort, is of light and heavy grades, according to the particular `class of cover to be provided and frequently said covers are lined with paper, or the like, .to provide a nicely iinishedarticle. Y

In the art of makingmovers` for check books, etc., the gummedcloth or tape connectingthe sides of the cover is` applied by hand after the `blank of material from which the cover is made is cut to provide said sides.

The purpose of the present invention has been to designa machine into whichga blank of cardboard, or similarstock, maybe fed, said blank being operated upon by `suitable `cutters so as to be separatedfto `form the sides of a book cover, and mechanism being employed for applying gummed tape, or clothto the separated portions `of the blank. The machine is also constructedto feed a `lining toy the cover sides; or sections of the cut blank, which `liningfis `adhesvely applied ina manner' which will be more fully pointed out hereinafter.

For `a full understanding of the present invention reference isto be had to the foli lowing description and to` the accompanying drawings, in which`` s Figure 1 is a longitudinal sectional view of "a machine' embodying the invention,` the section being taken` on` the `line A-B 'of Fig. 2. Fig; 2 is a top plan View ofthe ma-` Fig. 8 is a sectionalviewltaken on `the line chine. Fig."3 is a side elevation, certain parts being brokenlaway.` Fig. 4; is an end elevation ofthe machine. Fig. 5 is an enlarged detail view of the` cutters.` Fig. 6 is 4a sectional view of the `same. Fig. 7 is a diagrammatic `view showingthe variousfeed rolls in their relative positions and indicating the direction of rotation of said rolls.

C-Dlof Fig. l. F ig.` 9 is a top plan View of the glue tank or moistening means. i Figs. 10 and 11 are additional views of said device.V Fig.1 12 is a planlpviewof afblank cover inthe condition in which it is produced by this machine. Fig. 13j4 is a sectional `view of the cover shown in Fig. 12.

Fig. 14 is a View similar to Fig. `12, showing, a finishing covering paper, `or similar ma# terial applied to the side portions `ofthe` Fig. 15` isa plan View` of a cover of` very light material, as `formed by` the'presi cover.

ent machine, the action of thelcutters being fully illustrated] Fig. `16 is aviewfsimilar `to Fig.` 5 showing the type of cutter without` notches.

` Throughout the` following detail descrip#I tion fand on the several figures of the `drawings,similar partsare-referred toy by like reference characters.

y Patented oet. 6,1191@ The machine comprising the present in?" vention embodies a plurality of feeding rolls y which `carry the blank of :cardboard :or equivalent stock' from one end; of the machine tothe other.` The blank` as it `enters` which separate said blank into the sidesof the book cover. As the cut blankprogresses the machine is fed forward` by `a suitable` feedl chain and operated upon by cutters toward the delivery end ofthe machine, the` v separated portions'` of the blank have anioistened gummed `tape adhesively applied thereto so as to connectthe same,the` feed rolls by which the blank is moved affording means `for so applying the gummed tape and l.

, suitable shafts being supplied to carry rolls of finishing paper, cloth, or the like, which may be likewise applied tothe cut sections of the blank, according" tothe desire of the operator and havinginiviewthe special use to `which ,the covermay be put;`

. Referring to the drawings,

driving pulley carried )by the "shaft 2,.and 3 is aibearing for saidshaft.

4 denotes a driving` gear meshingiwithl an@y y idler gear 5, and 6` andll are other "gears y that meshr with anddrive `gears 7 and `12.

\ Shaft .7? supports the feed rolls 7*` and 7d,

and 12b and 12c` are cutters'which are attached by keys, or the like, to shaft `12Ysuit-` ably supported by the frameof the machine and fixedly carrying gears lllan'd 12;; A

sprocket chain 9 acts as a feeder for carryinggthe stock tothe feed rolls 17 and 7d, said chain `9passing around sprocket Wheels 8 and "10.` Pins on the chain 9are adapted to directly engage the stock in the `feeding operation. The traincof gearing` used on the` machine also includes an idler gear, 13.` driven fromgthe gear 11 and `meshing Iwith lthe driving gear 14, lthe latter operating in conjunction With a gear 15 Which'operates mesh and one of which is in mesh With the gear 16 to derive motion therefrom.

19 is aroll driven bysprocket and chain` connectionl'?1J :which leads to the roll 17a.

A "gear 21 v.meshes With 'the gear A22, said gears l:being mounted on shafts of the lrolls 212L and 22a respectively. The shafts upon which said gears are mounted are driven by va sprocket land Achain connection 20C vand gears 23 and 24 are in mesh and are driven by a sprocket and chain connection 22C.

25 is a spool for holding gummed tape, said tape l'being adapted to unroll from the spool 25 and passing over a moistening roll 26 mounted in the tank 26a, from whence said tape passes .upwardly between the rolls 14a and 15a., by Which rolls the tape is applied by pressure 'to one side of the sections of the blank which Yhas been previously .cut by means of the cutters 12v and 12c above mentioned. The arrangement of the gummed tape is shown clearly in Fig. 3. 27 is a second spool for gummed tape and similar spools are shovvn at 28, 30 and 32. Spool '32 is carried by shaft 32a Vjournaled in brackets 32b upstanding from the frame vof the machine.

The parts 28, 29 and 30 correspond respectivelyto the parts 25, 26 kand 27 and may be used, if it is Vdesired to apply more than 'a single strip of tape 'tothe sections ofthe blank as cut or separated in the Voperation of the machine. The spool 26 is driven 4by a belt 13b Vleading from the `.pulley 13a tothe pulley V26b on 'the shaft of theY moistening Vrol-126g.` The roll v29 is adapted to be `driven as ,shown in Fig. 3, a pulley and belt end of the shaft of the 'roll 26a.

r 31 denotes'a moistening lrollfor ,use in. 'moiste'mng ja tape running from .the spool 32.

'31e is a Water tank.

y 311 and 31 are shaftsover ivhich the tape 31'lpasses and `vvhich support the tank 31e, yas shown .in Figs. `Sand 6. p

111--11e is a clearer which operates lin the curved portionof one of 'thev-cuttersto main-4 tain 'thesame in unclog'ged condition..

7b, 12b, 18h, 2013,22b andv 241? are long screw A'bolts 'having suitable nuts-operating thereon for regiilating the pressure .between the 'feedv rolls.

the tank 31e on the shafts 31'b .and 31C.

It Willbe apparent thatWhen the blank of material is ,'fed by the chain .9 to theV lfeed `rolls '7 and 7d, said blank Will v'be carried gonward lto the cutters `12b and 12?,"the latter 'separating 'the blank 4into Lthree lpieces lor The shafts of the feed` rolls 17'a and 18L ,carry gears 18 Which interf 31g and 31h are hooks adapted to support' the cutting .of thel blank, as ydescribed above,-

may be discarded or adhesively conn'ectedto the gummed 'tape so as to "form .a reinforce` ment at the joint portionk of 'the book to i which the cover is applied.

As above premised, the sides of the boolk maybe covered by a. nishing paper or cloth, in which event, said paper or cloth may. be yfed tothe outermost ,cut portions ofthe blank from .any one of the -spools 25, '27, 28, 30 and 32.

*As shown in Figs.A 45. and '6, one of the cutters has its cutting edge preferably notched and this style of'cutter vvvill 'be used particularly for the purpose of operating uponvery light stock Which cannot be" handled Well in 'thismachine'if cut into separated sections. By using the notched `cutter, the stock Will be cut so that the sections forming the cover of the ybook are .held -together by narrow Webs instead of being entirely separated as vvvou'ld be the case with heavier stock, It Will be understood, furthermore, that'ifthe tape orcloth carried by the spool "27 or'equivalent shafts, is not gummed, the moistening tanks lreferred l-to hereinbefore -may contain liquid glue as an adhesiveto be applied to the tape as the latter lisfed tothe Work. A y

In 16 I have illustrated cutters simil. lar in construction and arrangement to' those seen .in Figs. '5 and '6, With the eXcep.

tion vthat the cutter disk shown asnotched v` Vin `Fig. '5 'is illustrated in Fig. '16 as possessed ofanuninterrupted periphery.V The.. said cutters -consistvof a disk 35 :having av peripherial lgroove 36 into which extends the periphery of the cutter disk 37.v

. In Figs. v13 and 14 are l.seen the cover blanks 'produced by a machine embodying.4 'the 'features of the present invention and and a back stiffening portion y39.., the portions '38 and 39 in vthe continued operation of the machine being connected by the strip 40 gummedA to 'the parts 38 and 3 9. 'ThisV .severingl action is accompanied by 'theoutting of ay strip of material from the blank foreach set of cutters, the severed strip 'being of a'wi'dth corresponding tothe thick- 1,113,022 f v s ness of the respective cutter, and thns the `slots 53 are produced.` Itfis to be noted that while the cutters sever the blank into the "respective parts, the feeding apparatus maintains the proper relation `of the parts of the blank so that the gummed strip may be readily applied and the parts given their final relation without manual adjustment.

` When it is desired to have a more rigid v what is claimed as new is:

l. In an apparatusof the class described, the combination of cutters, means for feeding a cover blank to the cutters, the cutters being positioned for cutting slots in the blank leaving a `stiening1 back portion be-` tween the side portions of theI blank and spaced therefrom, means for applying a` strip connecting the side portions and the` back portion, and means forguidingand maintaining the relative position of' said side portions and back portion during the application of the strip. 1 v

` 2. In mechanism ofthe class described, the combination with` means for `feeding a blank, of cutters disposed to act upon the blank while beingzfed, the said cutters being notched for forming spaced slots dividing" the blank into side portions and` an interf mediate back portion spaced `from the `zside `portions and havingwebs connecting `the back portion with the side portions, means for applying a strip connecting` the `side` i portions andthe back portion, and means w for guiding` the blank during the applica` tion of the strip. i i M In testimony whereof I afliX `my Signature 1 in presence of' two witnesses.:
